Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in Excellent condition, delivering the classic studio-style squeeze guitarists love. Simple four-control layout (Sustain, Level, Attack, Clipping) makes it easy to add smooth sustain, tighter dynamics, and extra punch without sacrificing clarity. Built in a rugged compact stompbox with standard 1/4" input/output and 9V DC center-negative power for pedalboard-friendly operation. A go-to compressor for clean tones, country snap, and lead consistency.
